Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Responding to environmental challenges: an initial assessment of higher education curricula needs by Australian planning professionals
No full textEnvironmental planning education has become crucial given the projected implications of climate change for human settlements and nature. However, despite the identified importance of educating planners with regards to sustainability and environmental issues, there has been limited discussion of the topic within literature. In particular, there has been little consultation with planning professionals about their perception of environmental planning curricula needs. This article addresses this need through the survey of planning professionals in Australia. Perceived gaps in environmental knowledge and skills of planners were identified. The key knowledge gaps highlighted included climate change and water management. The key skill gaps highlighted included critical thinking and independent inquiry. Implications for urban planning curricula including the need to revise planning curricula are discussed. The study has implications for and interest to other professional degrees of which environmental sustainability is a component
Barriers to implementing water efficiency practices in the built environment: The case of Melbourne and Bendigo, Australia
Get PDFWater supply in regional Victoria Australia: A review of the water cartage industry and willingness to pay for recycled water
No full textC1 - Journal Articles RefereedMany urban and regional areas of Australia have been facing severe drought over the past decade. This is particularly the case for most areas in the state of Victoria (located in the south east of the country). The management response to this situation has often been reactive with little thought about subsequent and long-term impacts. This paper reviews the water cartage industry in regional Victoria Australia which has developed in response to drought, suppling water in drought affected areas of the state. The review involved the survey of six water cartage businesses, and interviews with local government and water authority officers. The review found that the cost of the carted water is up to thirty-four times higher than the cost of the delivery of mains water in Australian cities and towns. Formal review of the water cartage industry and associated regulations is recommended to assess the environmental, social and economic impacts of water cartage. Secondly, and the paper benchmarks willingness to pay values for recycled water in a specific market segment of regional Victoria—Bendigo office workers (n=305). The contingent valuation method was used to elicit maximum willingness to pay for recycled water. The study found that participants were willing to pay on average A1.00=€0.50.US1.33/kL charged to Bendigo residents for the delivery of potable mains water which is subject to water use restrictions. The results of this study indicate that individuals facing prolonged restrictions to the use of water may be willing to pay a higher price for recycled water than policy makers may anticipate. The established water cartage industry which services the Bendigo area may have influenced the high willingness to pay for recycled water which was evident in the particular segment of the population surveyed. Lessons learnt from this research will be beneficial for catchment (watershed) management globally. An important component of sustainable water management is consideration of impacts across catchments
Is recycled water use risky? An Urban Australian community's perspective
No full textThe emergence of a global water crisis has seen the necessity for a sustainable approach to water management. Policies directed towards water recycling have been implemented in many regions of the world. In Australia, prolonged drought conditions in most major cities during the past decade have led to serious national calls for less drinking water to be used (Prime Minister’s Science Engineering and Innovation Council, 2003), and a strategic policy response from many State Governments, including bold targets for water recycling. A key consideration to the realisation of these policies is greater understanding of community attitudes to recycled water use, without which, a number of recycled water projects have failed (Hurlimann and McKay, 2004). Despite the critical nature of community attitudes, little research has been conducted, especially in relation to perception of risk, which has been found to be critical in the adoption of new technologies (Cvetkovich and Lofstedt, 1999). This paper investigates an urban Australian community’s perception of risk involved with using recycled water. Key findings include: perception of risk increased as the use of recycled water became increasingly personal. Perception of risk was significantly negatively related to trust, perception of fairness and information. Trust in the Water Authority to manage risk was significantly related to perception of trust, communication and integrity of the Authority.8
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
